Abstract:

In the current synthesized mass exchanger network targeting methods, no one considered piping costs in total costs estimations. This optimization technique is based on Pinch technology with detailed cost estimation. In the pinch targeting method as mass separating agent costs increases, mass exchanger area decreases. Further, as the mass flow rates of utility streams increases piping size increases. It means by increasing mass separating agent costs, mass exchanger cost decreases, but piping costs will increase. In the present work a case study is taken from open literature to study the effect of piping cost consideration in total cost estimation for optimum mass exchanger network design. The result obtained shows that optimum network configuration changes after accounting piping cost. Further, it is also found that piping cost consideration also affects the optimum minimum allowable composition difference (ϵ ) value.
